shoots in the normal plants but are sterile. They remain for the most part short, 
but some of the shoots in a bundle may grow out and develop into a long shoot 
like the mother shoot and bear a similar bunch of short shoots at the top (figs.

of Als, */; nat. size. C, f. filiformis very thin, infested by Ceratocolax Hartzii, dredged near Faaborg. Nat.size. D, f. stellata,

517 D, 518). This form is analogous to the f. stellata of Chondrus crispus, (comp. 
p- 505). The radiating shoots are sometimes repeatedly forked, and when, as will some- 
times happen, they are partly reflexed, the plants may remind one of f. uncinata of 
the said species. Some of the specimens referred by DARBISHIRE to Phyllophora par- 
vula (see above), belong to this form, while the other figured specimens probably 
represent other reduced loose forms of Phyllophora Brodiei.
